IMPROVEMENT IN MEATQHOFFERS.

Specification forming part of Leiters Patent No. 151.2%9, dated May 2G,187 g application filed March 17, 1874.

To all whom it may concern:

Be it known that we, LEVI HAGEN and Dnvin K. BURKHOLDER, of the city ofLanally found in that class of meatchopping ma-V chines which have arevolving block turned by screw-gear and cutters Vattached to longhorizontal arms.

The accompanying drawings, with the letters of reference marked thereon,with a brief description, will enable any one skilled in the art to makeand use our invention, in whieh- Figure l is a side elevation of themachine. Fig. 2 is a plan view. Fig. 3 is a central and rear verticalcrossseetion. Figs. 4 are detached portions or parts employed in the ad'justments.

We do not deem it necessary to describe the frame A B, revolving blockand ring S T, eogs U, and gearing G H O, as such are common, varyingmostly in the arrangement and combination of the parts employed.

The four or more flexible long horizontal arms, M, to which the choppersN are fastened by screw-rods and jam-nuts in the usual way, arecentrally connected, by pitman-like rods P, with a crank-shaft, on whichthe cranks L are diversified in their action on the arms M, so as tobring them down in a succession of blows. These iiexible arms M aresecured at their rear end, and by means of perforated lugs a a-nd capsf, by means of a rod which passes through them. The arms E E are hingedby a'pivot-bolt to the top of the central upright G of the machine. Oneof the said supporting lug-plates, a', is provided with an oblong slot,and made adjustable by a headed bolt,

^ Z, and thumb-screw nut Y, so as to keep the adjoining faces of thehinged caps f in close contact, to prevent lateral action in case ofwear.

In order to raise the choppers out of the way from the block, as well asto regulate the force of the blow, we aiiix the following devices to therear of the machine in connection with the cross-piece W. On each end oftheouter face guide-plates h aresecured by ordinary screws. These guidesare boxed out lengt tudinally for a slidebar, It, which is provided withan inclined ledge, i. There is also a vertical space boxed out in theseguides h to receive the hinged supports O. These supporting-bars Q havea pair of inclined lugs, SS,

on their inner faces, to receive the inclined ledges r between them.Within the vertical guides 7L, and between the outer plates t t, standthe arms a. The latch l confines the slide bar It and supporting-bars Q,in said guide-plates h. In order to operate the sliding bar R, it isfurnished at one end with a lug, a', which is perforated and providedwith a screw-thread for a screw, 7a, to work in, which is supported by aplate, m, secured at right angles to the sliding bar against the edge ofthe cross-piece WV.

As the supports Q are iiXed in their pivot to the frame ofthe machine,and at their upper end embrace the inclined ledge on the sliding bar, itfollows that the cross-piece lV, supporting the endsof the chopping-armsM,

will rise or fall by the sliding bar being either drawn one way or theother by the adjustingscrew, therebyinereasng orlessening the tension oraction of the flexible chopper-handles or arms M.

To raise the choppers from the block it is only necessary to raise thelatch Z, when the supporting and regulating bars Q can be drawn out fromits guide-chamber in h, and turned back to allow the cross-piece W, withits appliances, to drop down on the lower fixed frame. This combinedaction 'we call the drop-frame,

which elevates the choppers, and clears the block for being supplied orcleaned during the process of chopping or mineing meat.

The choppers are readily returned into their former position byreplacing the supports Q.

The dotted lines, Fig. l, indicate the action of our drop-frame, which,with the appliances and their arrangement, we deem new in meatchoppingmachines.

What we claim in a meat-chopping machine 1sl. The combination of thepivoted dropframe EVT, the adjusting-plates w a', hinged caps f, arms M,choppers N, cam-shaft and pitman P, constructed and operatingsubstantially in the manner and for the purpose set forth. I

2. The arrangement of the guide-boxes 7L t on the outer face of thecross-piece WV, the drop-frame E NV, the horizontal slide-bar R, withits inclined ledge r, the Vertical bar Q, provided with two inclinedledges, S S, and screw 7c, for the purpose mentioned.
